My dad bought some bubble coral about 3 weeks ago, it's slowly been looking worse and worse. Anyhow. he asked me if I would want it since it looks like it's dying...see if it would do better in my tank(since everything I've ever put in my tank has lived aside from fish).\n \nIs it a bad idea? I seem to remember them doing bad things when they died. How far to the brink can they go before it's too far for them to come back?
